See Figure 3 for the GND interface schematic. 2, 3, 6, 7, 10 to 15, 18, NIC No Internal Connection. These pins are not connected internally. However, all data was measured 19, 22, 23, 26 to 31 with these pins connected to RF/dc ground externally. 4, 5 RFIN/VGG RF Input (RFIN)/Gate Bias Control Voltage (VGG). This pin is a multifunction pin. The RFIN/VGG pin is dc-coupled with internal prematching and requires external matching to 50 Ω, as shown in Figure 38. See Figure 4 for the RFIN/VGG interface schematic. 20, 21 RFOUT/VDD RF Output (RFOUT)/Drain Bias Voltage (VDD). This is a multifunction pin. The RFOUT/VDD pin is dc-coupled and requires external matching to 50 Ω, as shown in Figure 38. See Figure 4 for the RFOUT/VDD interface schematic. EPAD Exposed Pad. The exposed pad must be connected to RF/dc ground. INTERFACE SCHEMATICSRFOUT/VDDGND 003 RFIN/VGG 004 13525- 13525- Figure 3. GND Interface Figure 4. RFIN/VGG and RFOUT/VDD Interface Rev.
